CompTIA Network+ (N10-007) — Question 493

A technician receives a report that Joe, an existing user, is unable to access the network. Joe confirms that he had full access the previous day. The change log is reviewed, and there have been no changes on Joe's computer or any network changes in the last week. The technician moves the connection to an adjacent location on the switch, and Joe is able to access the network. Which of the following is the MOST likely cause of this issue?

Answer options

• A. Incorrect pin-out
• B. Bad port
• C. Transceiver mismatch
• D. Incorrect cable type

Correct answer: B

Explanation

The correct answer is B, as moving the connection to a different port resolved the issue, suggesting that the original port was likely malfunctioning. Option A is unlikely since the pin-out would generally affect connectivity from the start, not change suddenly. Option C is not applicable as transceivers are typically not the issue when a simple switch of ports resolves connectivity. Option D is also unlikely, as an incorrect cable type would have affected connectivity from the beginning.
